Thompson Contender Barrel "Caps".

Recently purchased some Thompson Contender barrels - one in caliber 44 Mag and another in caliber 45 Colt/410. Both have screw-on "chokes" at the end of the barrels for shot loads. If I remove the chokes to shoot bullets, I have threads exposed inside the ends of the barrels. I understand there are some threaded caps that fit on the end of the barrels to protect the threads when the chokes are off.

I have been using a 44 Hot Shot barrel for 30 years and have never had a problem with the threads. I have never heard of the "caps", can't see a need for them. When I run out of Hot Shot 44 capsules I'll just go on using it for bullets. The capsules in 44 have been out of production for a number of years. I'm down to fewer than 300.

You can more than likely find a tread protector from most anyone that sells suppressors. Know what your tread pattern and size is needed. OR try T/C and see if they have one for you.

It's an internal thread.
I shot my friend's .44 mag hot shot barrel yesterday with some light wadcutter loads.
I've never heard of a thread protector for them. You use anti-seize or grease to protect the threads when shooting without the choke. There's more maintenance than a standard barrel, you have to clean out the grease often and replace it. a light coat of fresh grease anytime you put the choke back in.
